Please can you just confirm what versions of alsa & Nvidia you are using in the ID41.

Thanks

Hi Bushtech,

When I got it running (I'll explain that later), I got it running with Alsa 1.25 and Nvidia 295. The alsa that came with the snapshot I used came with Alsa 1.22 and that one did not detected the nvidia hda at all. After upgrading to 1.25 , it got listed as it should in aplay. When I got it running means that I did apt get upgrade last week and rebuild the image for the zotac mag and worked perfectly. I am doing apt upgrade tonight and going to try rebuilding the image ID41 and see how it handles audio and video.

Thanks for that info Tompin2. I will be watching with great interest as the sound on the ID41 is the issue I need to resolve. Curiously I am still on snap 26029 and I had video on the ID41 after doing libdvdcss & w32codecs. My alsa is still 0.22 & nvidia glx-260. Using UI2.

It is a bit of a pain. I am working on fixing it all.apt-get install linux-backports-modules-alsa-`uname -r`rebootThis will get them listed (aplay -l | grep -i 'hdmi')

You will likely have hw0 devices 3,7,8, and 9. It is almost always 3 or 7 on the id41, and seems to be completely random which. Others output on 9... others output on everything. Should look something like:

speaker-test -c 2 -l 1 -t sine -D hw:0,7etc based on the output of aplay where the 0 is the card and 7 is the device.

Now getting that to stick is another trick. In /usr/pluto/templates/asound.conf I would replace %MAIN_CARD% with 0,7 or whatever yours is.pcm.asym_hdmi { type asym playback.pcm "hdmi_playback" capture.pcm "plughw:%MAIN_CARD%"}

You may also have to addoptions snd-hda-intel model=auto oroptions snd-hda-intel enable_msi=0 index=-2to /etc/modprobe.d/alsa-base.conf to place the HDMI audo as card 0. For reasons I do not understand, it has to be card 0.

Keep in mind now, should you ever upgrade, you will have to go back and fix that templates hack.

I dislike giving hacks, but man... this stuff is so complicated and so different from case to case... I have not figured out a reliable way to do/undo it automagically, and I think it would involve a precursor menu to avwizard, including a reboot based on conditions.

Not to mention I don't actually have any equipment that doesn't "just work", so I just try and figure out how it works and take stabs in the dark.

Please report back with your results.

Hi L3,I decided to upgrade the core and start all from scratch. I downloaded the latest snapshot (yesterday) and video is no issue for neither MAG or ZBOX, It is the audio that is driving me crazy. On the MAG, I get audio with speaker test, and also within the multimedia kde controle module, but no sound at all when playing the videos, not even if the video is open directly at the kde desktop. With the ZBOX, I get no sound until I run the speaker test. Once I run the speakertest at the konsole, everything works perfect. Any hints?
